Calculator
Clean 4-function calculator with operator precedence and calculation history.
ℹ How it works
Unlike simple calculators that evaluate every keystroke immediately from left to right, this one applies standard operator precedence: × and ÷ bind before + and −, so 3 + 4 × 2 = 11, not 14. The full expression stays visible while you type, each result is kept in the history panel, and a click on a history entry recalls it into the next calculation. Everything runs locally in your browser.

FAQ
- Does this calculator respect the order of operations?
- Yes. Multiplication and division are evaluated before addition and subtraction, so 3 + 4 × 2 gives 11. Many basic calculators execute each keystroke immediately from left to right and would show 14.
- Which keyboard shortcuts are supported?
- Digits, the decimal point and + − * / work directly. Enter or = evaluates, Backspace deletes the last digit, Escape clears everything, and % divides the current entry by 100.
